Enum SchedulerKind 

pub enum SchedulerKind {
    Eevdf,
    Discover,
    Path,
    KernelBuiltin,
}

Discriminator for the test’s scheduler-spec shape on the --ktstr-shell-test=<NAME> wire format. Wire-byte-compatible with the prior stringly-typed "eevdf" | "discover" | "path" | "kernel_builtin" values via #[serde(rename_all = "snake_case")]; the typed enum replaces the stringly-typed boundary so a rename on either side (producer in dispatch::maybe_dispatch_shell_test, consumer in cargo_ktstr::misc::shell) is a compile error instead of a silent banner-emit-gate regression.

1:1 with crate::test_support::SchedulerSpec’s 4 variants; the payload data (scheduler binary name, KernelBuiltin enable/disable commands) rides separately on the descriptor’s scheduler_name / scheduler_enable_cmds / scheduler_disable_cmds fields so this type carries only the discriminator.

Variants

Eevdf

Kernel-default scheduling — no userspace binary, no kernel-builtin lifecycle. The no-scx control.

Discover

Userspace scx binary located via resolve_scheduler cascade (name-only, path is discovered at run time).

Path

Userspace scx binary at a fully-qualified path.

KernelBuiltin

In-kernel scheduling class activated via scheduler_enable_cmds before workload start, torn down via scheduler_disable_cmds on shell exit / test teardown.

Trait Implementations

impl Clone for SchedulerKind

fn clone(&self) -> SchedulerKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SchedulerKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SchedulerKind

fn default() -> SchedulerKind

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SchedulerKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SchedulerKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Renders the snake_case wire form ("eevdf", "discover", "path", "kernel_builtin") so banner format strings + log lines stay byte-compatible with the prior stringly-typed behavior.

impl From<&SchedulerSpec> for SchedulerKind

fn from(spec: &SchedulerSpec) -> Self

Single source of truth for the SchedulerSpec → SchedulerKind mapping. Exhaustive match so adding a 5th SchedulerSpec variant triggers a compile error here, forcing the discriminator to grow in lockstep.

impl Hash for SchedulerKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SchedulerKind

fn eq(&self, other: &SchedulerKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SchedulerKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SchedulerKind

impl Eq for SchedulerKind
